Shopping Notes…
Making the Offer:
The main challenge was that most of the listings showed odometer readings from before the vehicle went into loaner service.
In reality I found others advertised with as many as ~5,000 miles (which is an RV adjustment of ~$1000).
Decide how you want to address this in your offer. I didn’t address it at all, which was a risk. Be ready to talk about it if it comes up.
Note that some of the incentives are dealer’s discretion using flexible dealer cash from Cadillac.
From context in our discussions I know they added in 2 Flex Cash coupons to get to the final number (mentioned adding in $1k in “Cadillac money” the day after I walked away). When I tried to get them to add at least part of the other two, I was very politely invited to go shit in my hat.
Finding the Right Vehicle:
If you search new car listings on CarGurus you can sort search results by days in inventory (“Oldest Listings First”).
Among the oldest within 200 miles was the one I ended up with. This was not a mega-volume dealer, and while I didn’t get a unicorn by LH standards, it was clear that this level of discounting is an aberration in their normal course of business.
It’s easy to find loaners on Cadillac.com. From the inventory search tool, sort the results by distance (closest first). All new cars will be listed first by distance, and then all loaners at the end, also by distance.
Sorting Through the Choices:
Note that I had two requirements, AWD and not black.
Most of the loaners I found were either Luxury 1 or Sport 1. Combo of RV + MF was different for each but not materially so.
Since optional equipment is almost all unimportant to me, I was targeting the lowest MSRP vehicles.
AWD is a $3,500 option on either trim. I’d initially forgotten that RWD was even available, so I wasted some time upfront running calculators on RWDs. It’s easy to filter these out on Cadillac dot com, you just have to be smart enough to do it. 
Not every color is available in all trims, and nearly every exterior color is an added cost option. Luxury 1 choices:
The lowest possible MSRP for a 2025 AWD will be Argent Silver Metallic (standard) with no optional Black roof: $58,595 + $3,500 + $1,395 = $63,490.
The color choices alone on ours added $1,825, plus there’s SiriusXM ($299) and a bunch of accessories we wouldn’t have selected ($905), so in our example there are potentially avoidable options totaling $3,029.
